Be itknownthet lli/*ILL mi', linens, citizen o" the' United States, residing;i etv 'ielftenieh9 in the county of Eure snol Siete oiE Nebraska, has inventeol eertein new and useful ino proveniente in 'Dernountehle 'lire `iinis, of which the follirving is e, specification, reif ence being hen/f therein to the eccopenying dren/'ings The in-veniion reietes to demountehle rinus of the type useei in connection with pneuinetie automobile tires, and hes for its oh ject to provide n device o' this character o the split, rim type wherein the edjeoent abutting ends of the rim heve their renin body provicle with registering recesses, in which reoesses is pivotelly r'nounted et points spaced. from its encis, e lever which lever is l relatively Wide in relation to the mein body oi the rim, enel when the rim 'is 'expended' is in 'circumferential eineinent with the mein body oi the rino, thereby obvieting n huilry invverly ent-ending member.

l iur'sher object is to provide the lever .with e curved handle et one end of substentieliy the sainerelius es the riin ,anni adapted 'to closely engage the` inner side oia one end oft the rire. when the riin is ein psndeii, enci to reeeive in en aperture therein e rotatable locking boli'. which oooperetes with shoulders Within the aperture of the handle member for holding the hen Lile'znernher in closed position, seid handle member forming menne adapted to he grnspetl for moving the adjacent ends of the rim out. of abutting registration und contracting Athe rim upon a pivotal movement the lever, seid lever when in. extreme open position being vheld open. by the outward spring action of the rim.

Awfnrther ohieet is he rovitle the erh jacent ends of the riin lever with registering spaced lugs, between which lugs u member carried, by e felly is received for preventing circumferential movement of the n Wheel.

lilith the above and other objects lin View the invention resides in the combination emi arrangement of parts as hereinafter sei; forth, shown in the drawing, desorihe and claimed, it being understood that changes in 'the precise embodiment ofthe invention may be medewwithin the scope of what is cleaned Without departing from the spirit ofthe lnvention.,

Referring to rlreiving the numeral l' designates a. I {`lenio mt;zble riin, which rim comprises the enffiiuie. substantially et body iluernher 2 hevingflunges 3 adepte@ to grip and hold the clinoher flanges of en eutomobile tire. The rim l is split as at e, and has ies ends normally in abutting engagement es clearly shown in Figure i, when the rim is inuse on a, tire and Wheel elly. The adjacent ends oi' the body member 2 are provided with recesses 5, in which recesses is disposed e, lever 6, which is of suhsten` tieiiy the sume thickness as the body'memher i2, end disposed in the saine circumferential ere as the body member 2, thereby pre- 'ventiirgextensioin inwerdly and outwordiy, beyond the lines of the inner and outer longitudinel sec- Aperiphery of the bocly member 2. Lever 6 is pivoteliy connected. et? in the reoess at point spece from the outer end of the recess 5 and et 8 et e point spaced from the outer end of 'the other recess 5. @ne end oi the lever G adjacent the pivotal point 8 is provided with an zifeuate handle 9, Whih is reiet-iveiy thinr` und curved ,at substantially the saune are es the inner periphery of the 'body member 2, und positioned whereby when the lever 6 is in the position 'shown in Figure l, it will closely engage the inner periphery oi the riin enfi receive in the aperture l0 thereof the heed il oit e rotatable boit i2, which bolt when rotated to L `,oosition where its heed ll will be transversely disposed will, engage over the shouliloie .l2-3 of the aperture l() and securely hold 'said handle member und the lever in eX- tended position es shown in. Figure l, thereby rigidly holding; the (lemounta-ble rim in riuicl posiaion fil/'hen it 'is desired to contract the rim the operzitor grasps the handle member 9 and nieves the saine in the direction of lehe arrow o to the dotted line positions shown lin Figure l, which action will move the abutting ends oit-he .rim out of engagement and to the dotted line positions shown in Figure 1, there'b' cqntractin the rim, and allowing a tire to e removed t erefrom. The rim Ais held in contracted position also by the spring action 'of the rim when the lever is' in extreme open position.

The lever 6 is provided with spaced lugs 14, which lugs register with spaced lugs 15 carried by the inner periphery of the body member 2 of the rim at opposite sides or' the recess 5, and which lugs receive therebetween, When disposed on a wheel felly a securing bolt r lug, which will prevent circumferential movement of the rim on the elly. The lugs arepreferably'stamped from the body of the rim during the formation of the same thereby forming integral lugs and obviating the use of rivets. It is to be understood that the lugs 14 or 15 may.

be eliminated if so desired.

From the above it will be seen that means is provided in connection with a demountable rim whereby said rim may be easily and quickly contracted, and the abutting ends thereof moved into and out of engagement with each other. It will also be seen that the lever is-pivoted within recesses in the body 2 of the rim, thereby obviating the placing of fingers on Athe opposite sides of a lever which is a common difiiculty with devices' of thisl character wherein the lever forms arin section pivoted to adjacent ends of the split rim. It will also be seen that the device is compact in form and positive in itsoperation.

The invention having been set forth wha is claimed as new and useful is 1. The combination with adjacent abutting ends of a spiitrim having recesses in -curved handle member carried by one end of the lever and engaging the Iinner side of one end of the rim, a rotatable locking bolt carried by one end ,of the rim and extending into an aperture in said handle member, a bead carried by said locking bolt and cooperating with shoulders in the aperture of the handle member, spaced lugs carried by the lever, spaced lugs carried by the ends of the rim and registering with the lugs carried by the lever, said spaced lugs being adapted to receive therebetween a member carried by a felly.

2. The combination with the adjacent ends of a split demountable rim, said rim 'comprising a flat annular body member, tire receiving flanges carried by the 'opposite sides of the body member, a curved lever in the plane of the body member and having its ends pivotally connected in the inner ends of recesses carried by the body member, an inwardly oset curved handle carried by one end of the lever, said handle member engaging the inner side of ,the lbody member, locking means carried by the body member and cooperating with the handle and spaced registering'lugs carried by the inner` side of the body member adjacent their ends and registering with ,spaced lugs carried by the inner side of the lever.
